Answering a question no one seems to have asked, this four-door hatchback is an all-new model for BMW and mimics the company's larger 5-Series GT version. It's almost eight inches longer than the forthcoming 3-Series wagon and sits a little more than three inches higher.

This gives rear passengers more legroom than the 3-Series sedan or wagon and expands the cargo area by a cubic foot. The rear seatback are split 40-20-40 and fold accordingly.

The 3-Series GT will come with one of two engines, both of which are already available on the sedans. The base powerplant will be a direct-injected, 2.0-liter turbocharged four-cylinder engine making 240 horsepower and 255 pound-feet of torque.

More power is available in a turbocharged, inline six-cylinder engine. It wrings 300 horsepower and 300 pound-feet of torque from three liters.

Both models will be rear-wheel drive and will deliver the engine's power via an eight-speed automatic transmission.

Like the 3-Series sedan, the GT variant will come in four trim levels: Sport, Luxury, Modern and M Sport. BMW said all models will come with design features such as an active rear spoiler, four frameless doors, and a coupe-like profile.

Whether this new model attracts buyers remains to be seen, as it crowds BMW's lineup of cargo-friendly vehicles selling for less than $45,000. The company recently brought to the U.S. its small X1 crossover SUV, and the 3-Series wagon is on its way.

Meanwhile, BMW's equally curious 5 Series GT hatchback hasn't been a strong seller since arriving in the U.S. as a 2010 model.

We'll find out this summer, when these 3 Series GTs will go on sale as 2014 models. Pricing has yet to be announced, but a base 328i sedan sells for $37,745 and the GT will probably carry a premium over that.

Ford’s revolutionary aluminum-body F-150 pickup truck does well in most crash tests but is significantly more expensive to repair, according to an analysis by the Insurance Institute for Highway Safety.

Automakers say they are building the best cars ever, and there’s proof on the road. The average age of vehicles in the U.S. has climbed to a record 11.5 years, according to research firm IHS Automotive.
